I'an Newbie with Openstack and I learning it. I have installed Openstack following official doc on multinode https://docs.openstack.org/kolla-ansible/latest/user/quickstart.html
1 controller 1 storage 1 compute
Installation completed with no issue.
When I tried to create firt instance using GUI I had Issue [Error : No valid host was found. ].
Searching the issue, I discovered what nova-compute is not running, so I'am wondering if the issue come from this missing nova-compute.
openstack compute service list
+--------------------------------------+----------------+----------------+----------+---------+-------+----------------------------+

+--------------------------------------+----------------+----------------+----------+---------+-------+----------------------------+
And empty result:
openstack compute service list --service nova-compute
Reading doc seems others service like nova-api service and nova-api-metadata service are missing https://docs.openstack.org/nova/latest/install/get-started-compute.html
